... process, which can lead to significant damage to the heat exchanger and surrounding components. We employed FLUENT to simulate an abnormal transient in the heat exchangers for waste heat discharge system using a hybrid heat transfer model. The development of this model takes into consideration...

...Proceedings of the 2022 29th International Conference on Nuclear Engineering ICONE29 August 8-12, 2022, Virtual, Online ICONE29-92625 STRUCTURAL DESIGN AND DYNAMIC ANALYSIS OF THE HEAT EXCHANGER USED IN NUCLEAR FUEL TEST LOOP Huang Gang Nuclear Power Institute of China Chengdu, China School...

... Abstract A passive residual heat removal heat exchanger is used in several nuclear reactors to remove reactor core decay heat after severe accidents. In the late stages of a severe accident, the coolant level in a water storage tank may decrease and heat transfer tubes cannot be fully submerged...

... Abstract Passive residual heat removal heat exchanger (PRHR HX) is one of the important equipment in passive residual heat removal system (PRHRs) of marine nuclear power platform. The research on the condensation heat transfer characteristics of saturated steam in PRHR HX tube under tilting...

... of twist ratio than single strip inserts. Double strip inserts show suitability of helical screw insert in heat exchangers to compact the size of thermal applications. heat exchanger single and double strip helical screw inserts swirl flow friction factor thermal performance energy conversion...

... 08 04 2011 Thermochemical hydrogen cogeneration using heat of molten salt nuclear reactors (MSRs) is discussed in this paper. Sulfur-iodine and copper-chlorine cycles are taken as typical examples for analysis and discussion. It is found that the heat exchanger design is predominately...

... 23 02 2010 Reaction behavior of carbon dioxide (CO2) with a liquid sodium pool was experimentally investigated to understand the consequences of boundary tube failure in a sodium-CO2 heat exchanger. In this study, two kinds of experiments were carried out to investigate the reaction...

... properties of preferred ceramic materials to assess the viability and design reliability of ceramic heat exchangers for next generation high temperature heat exchangers. These analyses have been extended to conceptually compare the traditional shell and tube heat exchanger with shell and plate heat...

... The heat exchangers are always constructive elements of nuclear power plants and their dynamics is very important since they introduce a significant time lag in control actions. That’s why their dynamics cannot be ignored. On the basis of the accepted and critically clarified assumptions...

... was evaluated. The evaluation resulted in the MCO value of less than 0.01% (our target value: 0.1%). Nuclear Power Generation Heat Exchanger Design Steam Generator Moisture Separator Proceedings of ICONE 12 12th International Conference on Nuclear Engineering Proceedings of ICONE12 12th...

... with constant coefficients. Using the appropriate numerical simulation of the results derived, the dynamic of this process has been shown in the form of appropriate transient processes responses which quite well correspond to the real process behavior. Mathematical modelling heat exchanger distributed...

... Cross flow-induced vibrations tube bundle heat exchanger Bondgraph approach 20-SIM A considerable research has been carried out in the field of Cross-Flow Induced Vibrations (CFIV) in tube bundles of process exchangers and nuclear steam generators. Various excitation mechanisms...
